ADC122S706CIMT/NOPB

Analog To Digital Converters (ADC) Overview

The ADC122S706CIMT/NOPB is a dual-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes successive approximation register (SAR) architecture and operates with a maximum sampling rate of 700 kSPS per channel. The device supports single-ended or pseudo-differential input configurations and communicates via a standard SPI-compatible interface. It functions within an analog and digital supply voltage range of 2.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of approximately 73 dB and low power consumption of 1.2 mW at full speed. The component is housed in a 16-pin TSSOP package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free and RoHS compliance status. Confirm the specific package variant matches the design footprint requirements. Check for any recent product change notifications that may affect pinout or electrical characteristics. Ensure the supplier provides original manufacturer documentation for quality assurance purposes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 12-bit resolution is required at moderate speeds up to 700 kSPS. Consider the single-supply operation range if designing for 3.3 V or 5 V systems. Evaluate the power consumption against battery life requirements compared to higher-speed alternatives. Verify that the SPI interface timing meets the host processor's clock constraints.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC122S706 family of high-speed, low-power analog-to-digital converters. It shares architectural similarities with other SAR-based ADCs from Texas Instruments but offers specific dual-channel integration. The family is designed to replace discrete multiplexed solutions, reducing board space and complexity in multi-sensor applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements may include the ADC122S706CIZT/NOPB for QFN packaging or the ADC128S052 series for higher channel counts with lower speed. Verify pin compatibility and software register settings before substitution.
